The pathology and significance of cerebral amyloid angiopathy (CAA) is one of the more puzzling questions in dementia research. Although patients with Alzheimer's disease and/or vascular dementia often have CAA, the interaction between CAA and dementias is unclear. CAA's association with neurodegeneration may therefore have both diagnostic and therapeutic implications. For more information on how diffusion tensor imaging is helping to unlock the riddle of CAA, see Image of the Month, p. 10.
